onetool-mcp: OneTool MCP is a single MCP server that bundles 100+ tools — Brave search, Google, Context7, AWS, Playwright, Chrome DevTools, Excel, database operations, and more. Instead of registering each tool individually and burning context on their definitions, agents write short Python code to call any tool on demand. Anthropic engineering research backs this approach: code execution reduces token usage by over 98%, cutting costs dramatically when agents need many external tools.; turbovault: TurboVault is a dual-purpose toolkit providing a Rust SDK for building applications consuming markdown directories and a full-featured MCP server that works with Claude and other AI agents. It offers 44 specialized tools, supports multi-vault management, and uses BM25 search, link graph analysis, and more.
